How do charms work?

 When a sihirbaza  wants to create love magic that is to bring together two persons, she first needs to find out if this is possible by divination. After she has taken a large branch of hawthorn (Crataegus Oxyacantha) she then splits it into three parts of equal length. Then she waits for the fire in the fire place to tone down and then she places one branch upright into the ember which she names as the person she wishes to put her spell upon. The next branch she places right next to the first one, on its left side, in the hot ember 5 inches apart and names it as the person for whom she is creating the spell, and the third branch she places on the right side of the first one with the same distance apart but she doesn't name it. Then she watches to see what will happen. If the branch, the one she named as the person for whom she is creating the magic, falls as it is burning in the middle (named as the person she wishes to put her spell upon) then she is certain that her magic will succeed. However, if it happens that the un-named branch falls in the middle then it is clear that the magic will have no effect.
